The specific embodiment
The present invention is described further with reference to the accompanying drawings.
Lamp box of the present invention, comprise Lamp case frame and light-source system, described light-source system comprises a plurality of side by side compact arranged reflector modules, as shown in Figure 1, be the decomposing schematic representation according to the described reflector module of the embodiment of the invention, comprise reflecting plate 101, epipleural 102, lower side panel 103, left edge sealing 104, right edge sealing 105, and transparent front plate 106; Described front shroud 106 is oppositely arranged with reflecting plate 101, and by described up and down side plate 102,104 and left and right sides edge sealing 104,105 enclose and form an airtight spatial accommodation, be used for the airtight light source that holds, have a plurality of light source mounting holes on the described reflecting plate 101.Light source can be various, such as bulb, fluorescent tube or LED illuminator etc.
Wherein, the shape of described reflecting plate can be various, for example can be to form at least one groove, and as shown in Figure 2, reflecting plate 101 has two grooves, and described light source mounting hole 1011 then can be positioned at the bottom of described groove.Installation personnel can be arranged at light source on the reflecting plate in the spatial accommodation by this installing hole 1011, and the circuit accessories such as needed electric wire or circuit board can see through installing hole be installed in the reflecting plate back.Described reflecting plate can utilize a flanging 1012 that base middle part forms and side plate up and down to be connected by screw.Certainly, reflecting plate might not enclose by the design of this flanging and side plate up and down and be connected, in fact, if left and right sides edge sealing and reflecting plate are integrated, and left and right sides edge sealing with just can play the effect that connects reflecting plate that encloses being connected of side plate up and down, the effect of strengthening bonding strength has then further been played in the connection of flanging 1012.
The Main Function of left and right sides edge sealing is to be used for fixing front shroud, plays sealing function in the side simultaneously.The shape of edge sealing can be tabular or angle steel shape (forming the in-flanges shape) etc., all is fine, and particularly in order to fasten front shroud, generally all can form an in-flanges and withhold front shroud.But no matter which kind of shape because edge sealing has certain thickness and width, when it is positioned on the light path, can cause certain blocking to source light, forms low light level district; And because edge sealing is positioned at the edge of die set, when combination in lamp box connects when using side by side, low light level district can not get light filling and scope becomes large, therefore just easily forms dark space or underworld in the edge sealing position.
According to one embodiment of present invention, the part that left and right sides edge sealing can be higher than reflecting plate left and right sides side is formed by transparent material, certainly, also left and right sides edge sealing all can be made by transparent material, obviously also belongs to protection scope of the present invention.Because transparent material is less to the loss that light causes, and therefore, can avoid the formation of dark space.And left and right sides edge sealing be higher than the part of reflecting plate left and right sides side can be with front shroud one-body molded or split fix, the present invention does not limit this.
And according to another embodiment of the present invention, by the in-flanges on edge on the edge sealing of the left and right sides and engaging of front shroud, can fix front shroud.Front shroud can be fixed on by bonding mode in-flanges above or below; Also can front shroud be buckled in by the mode of pressing the below of in-flanges, front shroud is fixed.And have a plurality of hollow-out parts at described in-flanges, and by the design of hollow-out parts, can allow more light to pass through, also reduced blocking light.
The shape of hollow-out parts can be various, such as oval, square etc., or is the forms such as breach of sawtooth waveforms or square-wave-shaped, so long as can be the as far as possible few light that stops can also be fixed front shroud simultaneously and get final product.
And after the described in-flanges hollow out, easily deliquescing on the quality, support force to front shroud may be not enough, at this moment, according to embodiments of the invention, can also further form a stile in the in-flanges outer, as shown in Figure 3, stile 10511 has been so that the intensity of whole in-flanges 1051 has obtained enhancing, thereby the intensity of right edge sealing 105 is enhanced.
It can also be seen that in Fig. 3, right edge sealing 105 and can pegging graft by Plug Division 1052 between the side plate up and down enclose.Connected structure is not only firm, and has played each other the effect of position correction.
In addition, device of the present invention can further include at least one light source mounting bar 106, as shown in Figures 1 and 2, described mounting bar is arranged at the reflecting plate rear and is connected with described up and down side plate, and have a plurality of light resource installing section 1061 on the mounting bar, the position is corresponding with the light source mounting hole 1011 on the described reflecting plate.And in order to strengthen the intensity of mounting bar, can also increase a support member 107, be positioned at the below of mounting bar 106, and engage fixing with edge sealing, support mounting bar from the middle part, in order to avoid mounting bar subsides, also the intensity of whole reflecting plate has been played simultaneously the effect of enhancing.
Embodiment as shown in Figure 4, described mounting bar 106 can be grooved, and trough rim 1062 fits with described reflecting plate, is provided with a plurality of light source installation sheets 1061 in the notch, and described light resource installing section is positioned on the installation sheet.And the notch inner bottom part can also hold the circuit of light sources wire of drawing under the installation sheet etc., and cabling in the enclosure space in notch is very safe, convenient.
By mounting bar, can be in advance with light source install fixing after again integral installation in die set, convenient just as a fluorescent tube is installed, improved field-installed efficient; And mounting bar has been lived reflecting plate in supported underneath, has strengthened integrally-built stability; On the other hand, because the light source mounting bar carries and fixed light source, therefore simplified the structural design of the installation position in the reflecting plate.
The described transparent material of the embodiment of the invention, referring to can be through the material of light, all-transparent or translucent materials such as glass, PC plate, light-passing board, softbox, ground glass.
If adopt the all-transparent front shroud, then can be so that the light disposable transmission as much as possible that light source is sent to be gone out, the background color that relatively is suitable for picture exhibition is showed picture for white or light lamp box; And when adopting translucent front shroud (such as softbox, milk blank etc.), the light that then light source can be sent returns the part light reflection to reflector by translucent protecgulum, secondary reflection is gone out again, so, then be equivalent to carry out first shining again to the picture exhibition direction after the uniform treatment by the light that translucent protecgulum sends light source, so that it is softer on the whole to see through the light of translucent front shroud.
For instance, the background color of the displaying picture on being arranged on lamp box is that white or light color are when being, the light that light source sends by this displaying picture tunica albuginea or light film and part be reflected back toward the reflecting plate side, form again the secondary reflection irradiation to picture, by this round Multi reflection, utilize the diffraction of light effect, the light that light source can be sent carries out even soften handled; But, the background color of the displaying picture on being arranged on lamp box is that black or dark color are when being, the black film of this displaying picture or dark film will absorb the light that light source sends, and not can or seldom with light reflection back reflective plate side, this has just reduced the chance of secondary reflection, also reduced the even light effect reached via secondary reflection, this will show that picture produces bright wisp, affected the bandwagon effect of lamp box, can only be by increasing the thickness of lamp box, prolong light path and weaken bright wisp, but this can increase manufacturing cost undoubtedly, and affect attractive in appearance.
For this situation, if front shroud is set to translucent protecgulum, will the light that light source sends at first namely be carried out even soften handled in cassette interior by the secondary reflection that this translucent protecgulum forms, be equivalent to form a light box that sends uniform light, light after when light that light box sends arrives the black film of showing picture or dark film, being dodging, avoided showing that picture produces bright wisp, so just can reduce greatly the thickness of lamp box, because light path shortens, also increase overall brightness, or can reduce power consumption in the situation that brightness is constant.
The box body structure that the present invention forms by airtight spatial accommodation, light source in use is isolated from the outside, avoided the surface of light source directly to adsorb extraneous dust, even because the electrostatic interaction that light source produces, adsorbing outside transparent front after long-term the use has dust, also is easy to the dust that smooth transparent front is external and cleans out.
And the present invention can be come jointly to form by the combination of a plurality of reflector modules the overall reflective device plate of lamp box, therefore, installation or the debugging of whole lamp box reflecting system are finished in the operation that only needs a people just can pack into or split out single reflector module very easily.This is for the subway lamp box, and advantage is more obvious.For the consideration of security, before not allowing, the lamp box that is used for subway do not uncap, and can only be by the mode of opened at bottom the lamp box reflector to be carried out installation and maintenance.In the prior art situation, if there is a light source point to be damaged in the lamphouse light source, the operating space of lamp box is narrow and small owing to uncap in the end, and the maintenance personal keeps in repair after need to having to whole reflecting plate drawn off.And utilize the present invention, the module taking-up of being somebody's turn to do the light source place of damaging can be got final product.
According to one embodiment of present invention, the groove structure of reflecting plate 101 can be the spaced forward triangle of sawtooth waveforms or tool wave mode etc., can also be trapezoidal waveform.The groove structure of trapezoidal waveform, not only bottom land is the plane, and light source can conveniently be installed, and the adjacent slot body side surface of adjacent notches has a determining deviation, and forms a plane.If the adjacent notches close proximity, then the angle of adjacent slot body side surface formation easily forms bright line at the relative position of showing picture, has affected the bandwagon effect of picture; And the dual-side of adjacent two grooves is spaced a distance, form a plane, then because the light that this place, plane can not make light source send forms and assembles, avoided the appearance of bright line.Simultaneously, the plane of formation has also increased self intensity of reflecting plate, when conflicting when supporting with transparent front, and can be better and transparent front applying, the compactness of raising box body integral body.
The base of trapezoidal wave and the angle of dual-side are preferably more than or equal the lighting angle of light source, the side that is trapezoidal wave is in outside effective lighting angle of light source, the lighting angle of light source is the light scattering angle of light source, for example when the lighting angle of light source be that 40 degree-120 are when spending, if the angle of described base and side less than 120 degree, then can stop the direct projection light of light source, therefore, preferably, the angle of the base of trapezoidal wave and dual-side should be not less than 120 degree.Like this, because lamp box is secondary reflection equipment, the trapezoidal wave side of reflecting plate not only can not stop the direct projection light of light source, and the light that the direction from the picture exhibition plate can be reflected is reflected back the picture exhibition direction again.
Along the trapezoidal wave base to the top margin direction, the distance of described trapezoidal wave side and picture exhibition direction shortens gradually, and just, the light that is reflected back from the picture exhibition direction is also from trapezoidal wave base section to the both sides diminuendo, like this, we can see, the described side position nearest apart from the picture exhibition direction also is the most weak part of light that is reflected back from the picture exhibition direction, so can the shortest light path the most weak light be reflected back the picture exhibition direction again.Thus, along side by that analogy, the light of crescendo can be reflected back the picture exhibition direction with gradually long light path, realize the even of overall light.
The height that the height of described die set is preferably with described lamp box is complementary, certainly can be according to actual conditions to highly carrying out relative set, and for example height is less than the height of lamp box, can be installed in the lamp box get final product, novel this is not construed as limiting.
Further, the side of the groove of described reflecting plate can have many fins, and to increase the even light effect to secondary reflection light, these fins can be parallel with described groove notch edge, and on the stepped side that is distributed in described groove.The stairstepping of reflecting plate can be according to the quantity of the light source point of the size of reflecting plate and setting, extend, the ladder plane that wherein has in the stairstepping reflecting plate, the light that the transparent front aspect is reflected back is to try one's best the light path retroeflection short to transparent front, if be not to form projection at described end difference, and be still the inclined-plane of trough rim, so, light will be with the oblique retroeflection of larger light path to transparent front, exactly because and formed the ladder plane, the forward of then angle of retroeflection light can being tried one's best is in transparent front; Simultaneously, apart from light source zone far away, its light intensity is more weak, and since the gradient of cell body, the zone that light intensity is more weak, and its stair-stepping convex plane can more early receive light and with shorter light path retroeflection light, therefore, further play even light effect.
Stair-stepping convex plane only is for the area of controlling sensitive surface or height, and the area of sensitive surface and highly all be to have according to situation on the spot differently, stairstepping only is preferred embodiment.
